Account Closed Posted July 9, 2019 Share Posted July 9, 2019 Jussi, Do you expect that these new modulators will run on the Windows version of HQP? Have you been testing them on a Win10/64 system yet? From what I have been reading above, it looks questionable. I hope they do as I would love to try them. Link to comment

It would be still quite different from running something big and heavy as OS. So that would make a D4 iteration closer to Embedded's SQ? for, commercially, the package built for Ubuntu Server 18.04 LTS is a Desktop 4 purchase, upgrade afaic, correct ? Then I would just have to erase my Bootcamp partition and follow such recipe : https://www.lifewire.com/dual-boot-linux-and-mac-os-4125733 ? And then later simply do that on a more powerful machine ? New, for purchasing a GPU extension would not be a viable solution any longer due to the need of a as powerful processor as possible for EC modulators, correct? Since Audirvana works as front end, when I can borrow the MBP that has it, I find Embedded so handy dandy with just to have to press option at boot to select your images on usb stick... Would it be possible that D4 be recognised by Audirvana just as Embedded, as an alternative to Client? Link to comment

luisma Posted July 9, 2019 Share Posted July 9, 2019 I have to try the new modulators, DSD5, ASDM5 or ASDM7, where you guys find the bigger difference? I will have to go most likely to DSD128 Edit: And yes it depends on the filter used too I guess I will be using poli mqa mp On PCM is the RPDF dither new? Link to comment

Popular Post luisma Posted July 9, 2019 Popular Post Share Posted July 9, 2019 Listening to the new modulators now, can only do DSD128 with 7EC but I am pleasantly surprised, more by the fact that Jussi knowing how improved the modulators are haven't praised these too much publicly leaving the feedback to the community. I was exclusively doing straight PCM, not because HQPlayer is bad but because with my specific system (dac speakers etc) PCM is very detailed which I like, now I hate to have to accept this but software algorhtym alone may have improved over the dacs transistor ladder. I'm testing poli mqa mp 1x and nx, I can only imagine how other filters and DSD512 may sound. The modulator clarity and separation and noise it's amazing Last but certainly not least the algorhtym is someone's creation after much experience in this field, very well done sir, IMO this makes more of difference than filters when fed with high quality source content.

jimdukey Posted July 9, 2019 Share Posted July 9, 2019 I missed a few posts here. What new Modulators? I'm on 4.04 Desktop, and see the same list I've seen for a long while. Ive been using ASDM5, seen it recommended here for DSD 128. I seemed to like it more than ASDM7. I've noticed that some who get DSD 256 or 512 don't use those Modulators, but the ones not indicated for those rates instead. Link to comment

DSD512 doesn't work with the ASDM7EC as it is now, unless I find some more optimizations... My current server, with an AMD Ryzen 7 2700x, can easily handle upsampling all formats to DSD5EC DSD128. I'm hoping that the new AMD chips (or something else that's not too outrageously priced) can get us to EC at DSD512, at least with RedBook. Then it'll be possible to use the 1x (EC) and Nx (non EC if necessary) settings to automatically play all of the music at DSD512 with the best possible sound quality. 5 hours ago, luisma said: Listening to the new modulators now, can only do DSD128 with 7EC but I am pleasantly surprised, more by the fact that Jussi knowing how improved the modulators are haven't praised these too much publicly leaving the feedback to the community.

I couldn't agree more. These new EC modulators are fantastic. There are aspects of the sound that are lost going from DSD512 to DSD128, but there are also aspects that are gained from the EC modulators (available at the lower bitrate). Forced to choose, for now, I'll take the lower bit rate. EC is that good.

ted_b Posted July 10, 2019 Share Posted July 10, 2019 Jussi, I look forward to finally getting my year (and almost a half) long hiatus (not volunteered; move to Colorado-related) over and get back to my system. When I do I expect to be doing the same upsampling with my Holo Spring...that is, PCM to 352/384 and all DSD to DSD512. However, with the introduction of the new EC modulators I may be stymied with DSD512 until I update my up-til-now heavy lifting I7-6700k. Question: does the fact that I don't do PCM to DSD give my current server any chance to do DSD512 with the ECs, or is DSD64 to DSD512 still too much data? "We're all bozos on this bus"....F.T.

On 7/6/2019 at 4:22 PM, Miska said: Generally, regardless of modulators, I would say; DSD64 -> DSD128 is a huge step DSD128 -> DSD256 is still a big step DSD256 -> DSD512 is medium to small step DSD512 -> DSD1024 is small step If I read this correctly the second quote dealt with DSD to DSD upsampling.

Le Concombre Masqué Posted July 10, 2019 Share Posted July 10, 2019 INSOMNIA tonight ; listened to beloved Leonard Cohen's Ten New Songs 24/44 source & ext2/ASDM5EC to 128 output listened probably 1.5 to 2 dB louder than what I had in mind as reference level ; never sounded so gorgeous. Actually I got shivers. BUT in a half an hour time lapse there's been a good half a dozen cpu clock throttles alerts signalling from 1 to 1471 events Honestly I did not hear anything wrong, on the contrary, I was amazed So, is it because I was ecstatic or shouldn't we worry about cpu load (i keep it in the 25% ballpark, varying filters with rate) and heat and their negative impacts on SQ as long as it plays? Or is there a threshold (ie more alerts or more events per alert) at which we should question our perception if we keep being ecstatic ? Link to comment
sledwards Posted July 10, 2019 Share Posted July 10, 2019 The new ASDM7EC sounds wonderful. I am able to run it with poly-sinc-xtr-mp at DSD128 (upsampling Redbook) on my server, which has an Intel i7-8700 processor. Below are cpu process screen shots from htop for DSD128 and DSD256. Total cpu load for DSD128 is about 388% and 497% for DSD256, which noticeably stutters during playback. I am guessing this does correlate with the 100% load that comes and goes on one of the 8 cores. For comparison, Jussi is running his i7-8086K at DSD256 with a total cpu load of 225%. I looked at the Passmark performance scores for the two processors: i7-8700 = 15,156 and the i7-8086K = 16,691. Not a huge difference maybe, but I really don't know the correlation of the scores with respect to HQPlayer performance. So if I really want to run DSD256 with the new modulator (now), I could swap in the 8086K chip at the low price of 500 to 700 dollars! I think this would be premature. Hopefully there is another more cost effective solution that will even handle DSD512. Eager to hear what others are achieving. DSD128 DSD256 Link to comment
Popular Post Miska Posted July 10, 2019 Popular Post Share Posted July 10, 2019 i9-9900K could be also good candidate for CPU. With i7-8086K it is likely all about clock speed. All cores end up running at about 4.5 GHz clock. Without GPU's help the 8086K is also on the edge and needs some careful work on settings. Note, as usual, you can try to tune the core allocation in these edge cases by changing "multicore" attribute between "auto" and "1". This corresponds to grayed and checked in Desktop. I've done some optimizations and will probably put out 4.11.1 release with those. The same tunings/optimizations will also land in Desktop and Pro. Not much faster, but can better utilize multicore code path. Le Concombre Masqué and k6davis 2 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
sledwards Posted July 10, 2019 Share Posted July 10, 2019 Thanks for the suggestion Jussi. I forgot to mention I am running Embedded. I am not familiar with adjusting core allocation. How is this performed in Embedded? Link to comment
rando Posted July 10, 2019 Share Posted July 10, 2019 @Miska are we nearing the tipping point away from desktop processors into server hardware? Considering the possibility of Xeon with a Tesla GPU. The latter having more CUDA cores than a 2080ti is attractive. Link to comment

Considering the possibility of Xeon with a Tesla GPU. The latter having more CUDA cores than a 2080ti is attractive. GV100 would be interesting GPU, but nearly impossible to get. In Turing, Nvidia again has cut on the double precision floating point capacity. Server CPUs are not very nice because they tend to have lot of cores, but not particularly high clock frequencies. With GPU, critical point is "single thread" performance in a case where all cores are loaded, which could mean that CPU drops close to base clock frequency. Here are clock frequencies as reported by /proc/cpuinfo of the 8086K when playing DSD256 with ASDM7EC: cpu MHz : 4402.130 cpu MHz : 4402.126 cpu MHz : 4397.454 cpu MHz : 4354.592 cpu MHz : 4364.532 cpu MHz : 4400.641 cpu MHz : 4402.135 cpu MHz : 4402.150 cpu MHz : 4305.493 cpu MHz : 4343.871 cpu MHz : 4334.970 cpu MHz : 4379.682 rando 1 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
